CI = confidence intervals. DCS = decisional conflict scale. EPDS = Edinburgh postnatal depression scale. NA = not applicable. PDA = patient decision aid. STAI = state-trait anxiety inventory.

ANCOVA = analysis of covariance. CI = confidence intervals. DCS = decisional conflict scale. EPDS = Edinburgh postnatal depression scale. PDA = patient decision aid. STAI = state-trait anxiety inventory.
